What is CE labelling?
The purpose of CE labelling is to avoid technical obstacles
to trade within EFTA and the EU. The EU has introduced
the CE label as a simple way of showing whether a
product complies with the relevant EU directives. The CE
label says nothing about the specifications or quality of
the product. Frequency converters are regulated by 3 EU
directives:
The machinery directive (98/37/EEC)
All machines with critical moving parts are covered by the
machinery directive. Since a frequency converter is largely
electrical, it does not fall under the machinery directive.
However, if a frequency converter is supplied for use in a
machine, Danfoss provides information on safety aspects
relating to the frequency converter. Danfoss does this with
a manufacturer's declaration.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE labelled in accordance
with the low-voltage directive. The directive applies to all
electrical equipment and appliances used in the 50-1000 V
AC and the 75-1500 V DC voltage ranges. Danfoss CE
labels in accordance with the directive and issues a
declaration of conformity upon request.
The EMC directive (89/336/EEC)
EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means that the
mutual interference between different components/
appliances is so small that the functioning of the
appliances is not affected.
Danfoss CE labels in accordance with the directive and
issues a declaration of conformity upon request. To carry
out EMC-correct installation, this manual gives detailed
instructions for installation. In addition, Danfoss specifies
the standards which our different products comply with.
The frequency converter is most often used by profes-
sionals of the trade as a complex component forming part
of a larger appliance, system or installation. It must be
noted that the responsibility for the final EMC properties of
the appliance, system or installation rests with the installer.
1.6 Disposal
Do not dispose of equipment containing
electrical components together with
domestic waste.
Collect it separately in accordance with
local and currently valid legislation.
